Septic-to-sewer conversion in Palmetto Bay: the short answer

Septic-to-sewer conversion in Palmetto Bay depends on a public sewer line running past your property; most of the village is still on septic, with 6,158 parcels in the County's 2020 count. Where sewer is available, conversion means a new lateral, a plumbing permit, utility approval and abandoning the old tank under a Health Department permit.

The County's 2018 study expects the share of Palmetto Bay residential septic parcels with high peak groundwater to nearly double by 2030, and its policy is to prioritise sewer where septic systems are at risk. Until a line reaches your street, the practical step is keeping the existing system in good order, as the County's Connect 2 Protect programme advises.

When sewer is available, homestead single-family owners may qualify for up to $15,000 in grants or low-interest loans through the County's Septic-to-Sewer Financial Assistance Program, which estimates a typical conversion at about $15,000. Required permits include a pump-out and abandonment permit from the Department of Health and a plumbing permit.

Septic-to-sewer conversion in Palmetto Bay: questions

Who do I ask about sewer in Palmetto Bay?

The County tells residents of municipalities to contact their local water and sewer department. Miami-Dade Water and Sewer can confirm whether a gravity sewer abuts your lot.

What happens to my old tank after I connect?

It is pumped out and abandoned under a Department of Health permit, usually by filling it with sand or removing it, so it cannot collapse or collect water later.
